I noticed the articles do not support copy & paste functions like every other app. It would be useful to select a word or a phrase, copy it and paste it elsewhere.
Another useful feature would be selecting a word and use the standard dictionaries, eg. American English or British English, to look for the meaning of a word or a acronym.
iOS even offers the possibility of looking up for a word over the Internet.
Also, it would be nice to have the possibility of adding bookmarks for your preferred articles.
